DELETE WHERE EXISTS unexpected results

I want to delete certain rows from table USER_TBL.
Two tables are involved. USER_TBL and OWNER_TBL.

The entries that match BLAND type in OWNER table and who also have a
matching entry in USER table NAME but only for USER_TBL entries with
places equal to HOME.

DELETE FROM SP.TST_USER_TBL WHERE EXISTS
(SELECT SP.TST_USER_TBL.NAME FROM SP.TST_USER_TBL, SP.TST_OWNER_TBL WHERE
TYPE='BLAND' AND PLACE='HOME' AND
SP.TST_OWNER_TBL.NAME=SP.TST_USER_TBL.NAME)

Example :

OWNER_TBL USER_TBL

NAME TYPE PLACE NAME
BLAND BLAND WORK BLAND
LARRY BLAND HOME BLAND
MOE BLAND HOME LARRY
CURLY BLAND WORK LARRY
JOE BLAND HOME MOE

In the end I expect the USER_TBL to not contain the 3 HOME entries.
But what is happening is the whole USER_TBL is empty after the query.

Any ideas or tips.. Thanks.
